Title:
  Cisco Nexus ML2 mechanism fails on GRE networks

Status in networking-cisco:
  New

Bug description:
  There is a problem with Cisco Nexus ML2 mechanism and GRE networks.
  Function _port_action fails with NexusMissingRequiredFields if the
  port's network is not VLAN. So, this prevents port binding, and leads
  to completely non-working GRE networks.

  My proposed solution is to add a check in beginning of _port_action:

  if (segment and segment[api.NETWORK_TYPE] != p_const.TYPE_VLAN):
      return

  There is a similar check in _get_vlanid, but it is not enough
